APPARATUS FOR AUTOMATICALLY, lGNlTlNG, EXTINGUISHING, AND REGULATING GAS-ILIGHIS.

SPECIFICATION forming part of Letters Patent No. 239,856, dated April 5, 1881. Application filed December 16, 1880. (No model.) Patented in Germany April 9, 1880.

To all whom it may concern Be it known that I, JULIUS SGHiiLKE, of the city of Berlin, in the Kingdom of Prussia, and German Empire, have invented certain new and useful Improvements in Apparatus for Automatically Igniting, Extinguishing, and Regulating Gas Lights or Flames, of which the following is a specification.

My invention relates to improvements in automatical igniting and extinguishing, origniting, extinguishing, and regulating apparatus for gas lights or flames.

The objectof my said invention is to cause the automatical ignition of gas jets or flames as soon as the pressure is increased, to regulate the flow of gas to the burner, and to extinguish the flame by decreasing the said pressure. I.

The great objections raised against all apparatus constructed up to the present time are that they are too complicated and too expensive. Some are worked by means of electricity; others are operated by the increasing or diminishing of the pressure in the pipes; but all are either so expensive or so complicated that they cannot be introduced into practical use.

My said automatical apparatus combines simplicity and durability with accuracy and economy. The apparatus works with the greatest possible exaetitude, and answers all the requirements of a practical igniting, extinguishing, and regulating apparatus for street and other lights. Theapparatus is so'arranged that the street or other flame is ignited as soon as the pressure in the main is increased, and extinguished as soon as the pressure is decreased, and'so that the tlowof gas to the If it is intended that certain lights should continue to burn with low or day pressure the apparatus and the valves or disks in the same are arranged accordingly.

' It has been proved that by employing my said apparatus for igniting, extinguishing, and regulating street or other lights or flames a saving of twenty-five per cent. has been achieved 5 and besides this lamp-lighters are no longer required. As soon as the pressure in the mains and branch pipes is increased the entire number of street or other lights are ignited. As soon as the pressure is lowered all the lights are extinguished and the tiny auxiliary flame ignited. This auxiliary burner is so arranged that it either continues permanently in actionthat is, the flame burns constantly night and day or'the auxiliary flame burns with a scarcely perceptible flamedurin g the day-time or by low pressure, but is extinguished as soon as the pressure is increased, and reignited as soon as the pressure is decreased.

Figure 1 is a section of an apparatus whereby the auxiliary flame burns by low pressure, but is extinguished as soon as the pressure has been increased enough to raise the regulater-valve. Before this auxiliary flame is extinguished it has ignited the flame in the chief burner. In this figure the auxiliary flame is burning, whereas the gas -flow to the chief burner is cutoff. Fig. 2 is a section of the burner, showing the position of the parts by night or high pressure. The auxiliary flame is extinguished and the chief flame ignited. As will be seen from thedrawings, the two flames come alternately into operation. Figs. 3 and 4 show the sections of two modifications of this arrangement. In Fig. 3 the rear part of the burner acts as a stop to' the small valve or movable disk, whereas in Fig. 4 this valve or disk is entirely omitted. Fig. 5shows a section of a modification whereby the auxiliary flameburns constantly, and is neither extinguished by high or low pressure. This is the simplest kind of apparatus, is without regulator, and with only one movable disk or valve. Fig.6'shows another form, wherein the auxiliary flame burns constantly, the regulating devicebeing also used.

Like letters denote like parts in all the figures.

A is the auxiliary burner, B the ordinary bats-win g orother similarburne'r; or the burner shown can be replaced by an Argand or other burner, and the position of the auxiliary burner altered accordingly.

O is the upper part of the case of the apparatus, which is bored to receive the burner, and is screwed onto the lower part, D, of the apparatus. These parts are so provided-with cavities that avalve-box or gas-chamber, E, is formed. In this valve-box E is a valve or disk, F, with a pin or spindle, G, which moves up and down in the boring H of the lower part, D, of the case G D, and is so provided with a notch or groove that the canal N, leading to the small auxiliary burner A, is-broughtinto connection with the valve-box or gas-chamber E when the pressure is decreased, so that the valve or disk F is lowered. As soon as the pressure is so reduced that the gas is no longer powerful enough to hold up the disk F the connection with the burner B is cut off, the flame extinguished, the gas directed into the canal N leading to the auxiliary burner A, and this said gas ignited, so as to produce the igniting-flame for the chief burner B. It will thus be seen that once put into operation the one flame ignites the other before it is extinguished, and that a perfect automatical igniting and extinguishing apparatus is produced on an exceedingly cheap scale, Whereas the valve or disk F acts as a perfect regulator, permitting only a desired quantity of gas to pass to the burner. As soon as the pressure is .increased beyond the required limit by the extinguishing of the house or other lights or other means, the valve F is raised accordingly, so that although a larger quantity of gas can enter the valve-box or gas-chamber E beneath .the valve or disk F, the gas-chamber above the valve is reduced in size. In this manner the flow of gas to the burner is kept perfectly equable, the flame burns without causing the well-known unpleasant hissing noise, and an enormous saving of gas is attained.

G is a perforated disk, which is inserted in the boring of the part 0 to form a stop for the valve H, which cuts off the connection between the valve-box E and the burner B as soon as the pressure is lowered and the valve or disk F sinks onto its seat.

J is the boring or borings in the lower part of the case D, by which the gas from the gaspipe enters the valve-box or gas-chamber E.

In Fig. 3 the burner forms the stop for the valve or disk H, and the disk or valve F fits so onto the raised ring K at the bottom of the gas-chamber or valve-box E that the gas is cut off from entering the said chamber by low pressure, but escapes direct from the annular space formed between the bottom of the chamber and the lower surface of the valve or disk F into the canal N leading to the small or day burner. As soon as the valve F is raised by an increased pressure gas flows to the burner B and the burner A is extinguished.

According to the arrangements shown in Fig. 5 the auxiliary flame A remains continuously in operation, whereas the flow of gas to the burner B is cut off by means of the valve I H as soon as the pressure is decreased, so that the said gas flows through the perforations L into the canal N leading to the continuouslyburning auxiliary burner. The regulator is omitted in this arrangement. 1

In Fig. 6 a continuously burning auxiliary flame is also employed, but with the addition of the regulating disk or valve F. When the valves H and F are closed by low pressure sufficient gas flows through the cavity or cut made in any desired part of the annular projection K, or through a boring in the valve or disk F, to supply the said auxiliary flame with gas.

Instead of employing the ring K, the disk or valve F can be provided with a pin or pins, or stop or stops can be formed on the inner walls of the case.

M is a cap, which is placed over the auxiliary flame A, and is provided with a slot for the flame to pass through. This cap is for the purpose of preventing the auxiliary flame from being extinguished by the wind.

I will now describe the operation of my said apparatus with reference to Figs. 1 and 2, the apparatus being fixed and the auxiliary flame ignited.

The gas from the gas-pipe flows through the boring or borings J into the valve-chamber E, and from thence, through the notch or groove in the pin or spindle of the valve or disk F, into the canal Nleading to the auxiliary flame A. As soon as the pressure in the main is increased the regulating valve or disk F is raised, the gas flows around the periphery of the same, or through cavities or cuts in the said periphery, into the upper part of the chamber E, raises the valve H, and escapes to the burner B, when it is ignited by the auxiliary flame A. In the meantime the spindle G of the valve or disk F having also been raised the connection between the valve-chamber E Y and the canal N leading to the auxiliary flame is cut off and the said auxiliary flame extinguished. On the pressure in the main being lowered the reverse action ensues, the flame of the burner B is extinguished, and the flame of the burner A ignited.

Having now fully described the nature of my said invention and the manner in which the same is carried into effect, I desire it to be understood that I do not confine myself to the dimensions shown in the drawings, or to the special disposition of the parts, or the form of the same as shown in the accompanying figures, as these can be varied without departing from the nature of my invention; but

What I do claim, and desire to have protected by Letters Patent, is
